Hodgkin-Huxley model has been reframed to incorporate the physical parameters of fluid inside the axon. The reframed model comprises of set of partial differential equations containing the physical parameters: density, mass fraction of sodium, potassium and chlorine ions, longitudinal diffusivity of ions and rate of additions of ions along with the temperature. Obtained conduction velocity of 19.5m/sec at a temperature of 18.5 degree celcius and conduction velocity dependency on temperature within the range 5 to 25 degree celcius are two important results that strongly validate the proposed model. The behavior of all the physical parameters has been characterized with respect to the action potential. Action potential conduction velocity along with axoplasmic fluid viscosity has been characterized with respect to different temperatures. Longitudinal diffusivity of ions is also quantified.

Traumatic brain injury (TBI) and subsequent post-traumatic epilepsy (PTE) often impair daily activities and mental health (MH), which contribute to long-term TBI-related disability. PTE also affects driving capacity, which impacts functional independence, community participation, and satisfaction with life (SWL). However, studies evaluating the collective impact of PTE on multidimensional outcomes are lacking.

Hydroxycinnamic acid derivatives are a class of phenolic acid compounds, including sinapic acid, ferulic acid, and caffeic acid, which are widely found in plants. This experiment was conducted to study the effects of hydroxycinnamic acid derivatives (sinapic acid, ferulic acid, and caffeic acid) on the growth performance, muscle physical parameters, and intestinal morphology of tilapia. A total of 320 tilapia fingerlings (9.

Unlabelled: One common gait issue associated with advanced Parkinson's disease (PD) is freezing of gait (FoG). FoG impacts approximately half of people with PD and negatively impacts quality of life. Studies have suggested that anxiety may contribute to FoG.

Aim: Posterior tibial nerve stimulation (PTNS) might stimulate the sacral nerves and lead to work pelvic floor muscles. We evaluated to effects of PTNS on continence results after extraperitoneal laparoscopic radical prostatectomy (eLRP) with three trocars during early post operative period.
Methods: Prospectively recorded data of eLRP with three trocars was retrospectively reviewed for continence results between January 2017 and April 2024.

This article presents data measured in 44 farms covering a range of cropping practices, soil, and production parameters under contrasted types of crop management: conventional and conservation agriculture. Eighty-six winter wheat fields in Northwestern France were monitored for two growing seasons (2021-2023). The dataset encompasses data about cropping practices (tillage, soil cover, rotation, pesticide use, nutrition), soils (chemical, biological, and physical parameters, including texture), and grain production (nutritional, technological, and sanitary indicators).
